This part of ISO 11148 specifies safety requirements for hand-held non-electric power tools fitted with collets (hereinafter “die grinders”) intended for grinding and surface finishing and chamfering using mounted points, burrs and files and small wire brushes and other accessories mounted on shanks. The die grinders can be powered by compressed air, hydraulic fluid or internal combustion engines and are intended to be used by one operator and supported by the operator's hand or hands, with or without a suspension, e.g. a balancer. NOTE 1 At the time of publication, no die grinders driven by internal combustion engines are known. Once these are identified, it is intended to amend this part of ISO 11148 to include such power tools. This part of ISO 11148 is applicable to: - angle die grinders; - reciprocating files; - rotary files; - straight die grinders. NOTE 2 For examples of die grinders, see Annex B. NOTE 3 Grinders without collets, for use with cones and plugs with threaded inserts, are covered by ISO 11148-7. This part of ISO 11148 deals with all significant hazards, hazardous situations or hazardous events relevant to die grinders when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer, with the exception of the use of die grinders in potentially explosive atmospheres. NOTE 4 EN 13463-1 gives requirements for non-electrical equipment for potentially explosive atmospheres.
